What Every CLR Developer Must Know Before Writing Code

A. Writing Code Programmers working on a large project have just received a task to write exactly m lines of code. There are n programmers working on a project, the i-th of them makes exactly ai bugs in every line of code that he writes. Let's call a

题目传送门 1 /* 2 题意:n个程序员,每个人每行写a[i]个bug,现在写m行,最多出现b个bug,问可能的方案有几个 3 完全背包:dp[i][j][k] 表示i个人,j行,k个bug dp[0][0][0] = 1 表示不选择人的时候所有的bug的种类犯错误都只有一种 4 dp[i][j][k] += dp[i%2][j-1][k-a[i]]: 5 错误示范:dp[i][j][k] += dp[i-1][j-l][k-l*a[i]]; 其实要从上一行的状态推出,即少一行 6 内存限制,

题意:n个程序员一起写m行代码,第i个程序员每写一行有a[i]个bug,求总bug不超过b的分配方案有多少种 分析:这题很像完全背包,不过求的不是最大/最小bug数,求的是bug数小于上限的分配方案.所以这题要用三维dp dp[i][j][k]表示前i个个程序员总共写了j行代码产生了k个bug时的plan数,这题有两种转移:1)第i个程序员再写一行:2)换第i+1号程序员写 所以方程:dp[i][j][k]=dp[i-1][j][k]+dp[i][j-1][k-a[i]],注意:程序员可能一行都

有n个程序,这n个程序运作产生m行代码,但是每个程序产生的BUG总和不能超过b, 给出每个程序产生的代码,每行会产生ai个BUG,问在总BUG不超过b的情况下, 我们有几种选择方法思路:看懂了题意之后就是一个完全背包题了 定义dp[ i ][ j ][ k ] 表示前 i 个程序员,已经写了 j 行代码, 已经产生了 k 个 bugs . 根据题意,得知第 i 个程序员会写 r 行代码,那么相当于 dp[ i ][ j ][ k ] += dp[i - 1][j - r][k - ra[ i ]
